COMBINATION BICYCLE-LOCK.

SPECIFICATION forming part of Letters Patent No. 576,835, dated February9, 1897.

` Application filed May 9, 1896. Serial No. 590,932. (No model.)

.To all whom t may concern:

Be it known that I, SAMUEL W. COLLINS, a citizen of the United States,residing at Kokomo, in the county of Howard and State of Indiana, haveinvented certain new and useful Improvements in a Combination Bicycle-Lock; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the1o art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

My invention relates to improvements in combination bicycle-locks ofthat class that arev permanently attached to vthe bicycleframe andadapted to securely lock the steering-post against turning Within theframezo head, and has for its objects, iirst, to provide a lock of thatclass that is always in position; second, that can be locked andunlocked without the use of a key; third, that is susceptible of a greatnumber of changes of the corn- 2 5 bination; fourth, that may be changedreadily from one combination to another; fifth, that will add but littleWeight to the bicycle; sixth, that will not be in the way of the rider,and, seventh, that may be built upon the bicycle 3o or attached theretoafter the machine is finished.

With these objects in view my invention consists in the construction andcombination of parts shown in the accompanying draw- 3 5 ings, anddescribed in the following specification.

In the drawings, Figure lis a view of a portion of a bicycle, showingthe lock thereon. v

Fig. 2 is a cross-sectional view taken on the 4o line 2 2 of Figs. l and3. Fig. 3 is a vertical sectional view of the lock and that portion ofthe bicycle-frame to which it attaches. Fig.

4 is a top plan view showing the outer rings or tumblers in section.Fig. 5 is a crosssection of one of the outer rings or tumblers. Fig. 6is an enlarged fragmental view of a section of one of the inner notchedtumblers and the outer ring. Fig. '7 is a perspective View, partly insection, of the lock-opening ring or tumbler, and Fig. 8 is a sectionalView showing a modified form of construction.

A is the handle-bar.

B is the frame-head.

' C is the steering-post.

D is the horizontal top tube of the frame.

E is the central core sustaining the locking-bolt.

F is the retaining-ring, which holds the tumblers and friction-rings upagainst each other.

G is the lock-operating ring or tumbler.

H H are the separating-rings between the tumblers.

I I are vthe notched inner tumblers.

Y J J are the outer rings or tumblers having the combination-numbers.

K is the locking-bolt.

L is the spring which presses the bolt K forward when it is released bythe tumbler G.

The outer rings J are provided with a series of numbers and graduationson the outside, and each of them have the V-shaped pro jection a locatedupon the inner face at the desired point. This projection ay enters theVshaped notches b, extending across the outer faces of the tumblers I.The tumblers I are each provided with a slot c in the inner face, andthe outer face above the slot c is plain, as at d.

The operating-ring Ghas on its inner face an open collar e, one end ofAwhich is narrower at the opening than the other and gradually widenstoward the center. It is also provided with a shield f, which is adaptedto project over a portion of the outer rings J, and has a semicircularnotch g in its outer edge, whereby the screw h, securing theretaining-ring F, may be removed. It is also provided with a mark fr',which is directly over the openin g in the open collar e, secured to theinside. The notched tumblers I are not as wide as the outer rings J, andthe dif ference in width is lled by the separatingrings H. These ringsare immovable on the tube D and have an opening corresponding with theWidth of the bolt K, thereby allowing the projections j thereon to passsaid rings Il. These rings serve to separate the tuniblers I and preventthe adjacent tumbler from turning by friction when the next one to it isbeing turned.

The bolt K is adapted to slide in a slot l1; in the core E, and in theslot 7c in the hori- Zontal tube D, and has the projections J upon itsupper edge, which are adapted to pass the slots c in the notchedtumblers I, the openings in the separati ng-rin gs II, and the openingin the open collar e. The lower part of the rear end of the bolt K iscutaway and is provided with a stud I, around which one end of thespring L is coiled. The core E has an opening of suiiicient size toreceive the coilspring L. The front end of the bolt Kpasses through anopening in the Wall of the frame-head B and enters a slot on in thesteering-post C, when said steering-post is turned so as to bring theslot m opposite the bolt K. The spring L presses the bolt forward intosaid slot m, provided the ring G is turned so as to bring the opening inthe open collar c in line with the projections upon the bolt K. When inthis position, the shield j' will be opposite the side of the tube D andthe mark i will be directly on top of said tube. Then movedin thisposition, the semi.- circular notch g passes the screw h, and therebypreventsits removal. The tumblers I and the outer rings J, which movetogether by rea-son of the notches ZJ and the projections ct engagingeach other, are then turned, which carries the slots c in the tumblers Iout of line with the projections j upon the bolt K, thereby preventingthe bolt K slipping back, and holding the forward end in the slot m inthe steering-post. In this position the operating-ring G cannot berotated by reason .of the rear projection j on the bolt K being heldagainst a rear movement by reason ofthe forward projections j not beingable to pass the notched tumblers I. The slot m being in the side of thesteering-post, it will be seen that the front wheel will beturnedsidewise when locked, thus rendering it impossible to propel thebicycle except in a small circle.

To unlock the wheel, the rings J are turned until the numbers on thering to which the combination is set come opposite the mark 'i upon thering G. This brings the openings c in the tumblers I in line with theprojection j on the bolt K. The ring G is then turned, the rearprojection j on the bolt K being engaged by the narrow end of the opencollar, and thereby draws the bolt K back. This brings the otherprojections into the slots c on the inside of the tumblers Lwhichprevents them from being turned. The shieldfis then `on top of the tube,as shown in Fig. 1, and

covers the numbers to which the combination is set and prevents any onefrom observing the numbers of the combination when the wheel isunlocked. The Wheel is quickly locked by turning the ring G until themark t is opposite the numbers of the combination, then turning thesteering-post until the opening m comes opposite the bolt K.Y A slightturn of the rings J prevents the withdrawal of the bolt and throws thecombination out. To change the combination, the screw 7L is removed andthe securing-ring F slid back on the tube D. The ring Gandseparating-ring I-I are slid back against F and the outer ring J slippedoff of the notched tumbler I. The ring J is then turned until thedesired number comes on top, directly opposite the plain portion CZ ofthe tumbler I, and is then slipped back. when the Vsh aped projection awill enter a corresponding V-shaped notch in the tumbler J. Either oneor both of the sets of numbers may be changed in the same manner, whenall the rings and tumblers are pushed back into place and the screw hagain inserted, holding the lock securely `in place.

It will be seen that the combination is susceptible of a large number ofchangesand that it will be impossible to open the lock without workingthe combination or destroying the frame.

In Fig. 8 is shown a modiiiediiform of the lock adapted to be attachedto a bicycle already built, as it is obvious the constructions abovedescribed can only be advantageously attached when the frame is beingput together, The arrangement and .construction .of the rings J and thetumblers I are the same, and the bolt K operates in the same manner.;but the lock-operating ring G is located next the steering-post, and thecore E has a flange `n on the outer end, which `is equal in diameter tothe diameter of the rings J, and serv-es to hold them in place on thecore The bolt K is slightly dilterent in shape, but the principle andmanner of locking is the same as in the lock above described.
